21 Claims.

This invention relates to printing machines and the salient object is to provide an auxiliary printing mechanism in the machine and an ancillary object is to regulate the operation of the auxiliary printing mechanism in accordance with the operation of the machine.

While my invention is susceptible to many and varied uses, an illustrative use is in the printing of the variable information on tax bills and the like. This variable information is printed from printing devices passed through a suitable printing machine. The printing devices are arranged in the same sequence as the sequence of the items on the assessment roll and, after passing through the machine, the devices are collected and stored, in the well understood manner, the sequence be ing maintained. By repeatedly passing the printing devices through the machine the variable information on original tax bills, delinquent notices, and other similar matter, may be printed. To facilitate cross-reference and the like between the bills and the roll, the items on the roll are numbered, usually consecutively, and the bills and other notices are correspondingly numbered, .and the auxiliary printing mechanism, forming my invention, may be employed to perform this numbering operation. As long as the sequence of the printing devices is maintained constant with the sequence of the items on the assessment roll the numbering of the bills may easily be maintained constant by operating the auxiliary printing mechanism as each printing device passes through the machine. However, if a section of property or the like, represented by one item on the assessment roll, be divided, it will be necessary, to add a printing device for each of the added subdivisions and thus the corresponding sequence between the printing devices and the assessment roll will be destroyed. From this it is apparent that it would not be practical to provide the numbers directly on the printing devices,

and it is also apparent that some means must be provided for interrupting the operation of the auxiliary printing mechanism, when added plates are passed through the machine, for, if the auxiliary mechanism is permitted to operate and number when an added printing device is passed through the machine, the numbering of subsequent printing devices would not correspond with the assessment roll. To care for this, and analogous conditions when the machine is used for other purposes, it is another object of my invention to providean auxiliary printing mechanism which will only operate when certain printing devices are passed through the machine.

The assessment roll for an ensuing year is usually made up about the middle of the preceding year. This roll is made up from the printing devices, these devices being passed through the machine and, when this is done, every printing 0 device is used in a printing operation and the impressions made from each of such devices are numbered as they are made on the assessment roll. However, after the new assessment roll has been made up, it is necessary that further printing operations becarried out in accordance with the previous or old assessment roll and that the added devices not be used in a printing operation until the printing is to be performed in accordance with the newly made up assessment roll. in It is, therefore, a further object of my invention to provide an auxiliary printing mechanism which may be operated either intermittently or consecutively.

Further objects 01": theinvention are to provide an auxiliary printing mechanism which may be regulated from the printing devices passed through the machine and to provide a mechanism which may be electrically controlled.

Still further objects of the invention are to provide an auxiliary printing mechanism with which a numbering device may be associated and to provide a numbering device which will accumulate upon each operation of the auxiliary printing mechanism.

In the drawings, indicates the frame of a printing machine of the character with which my invention is adapted to be associated. Such a printing machine may be a so-called addressing or a duplicating machine, and a typical machine of this character is disclosed in the patent to Duncan, No. 1,681,525, patented August 21, 1928. In such machines a motor, diagrammatically shown and indicated by 11 in Fig. 9, operates the various mechanisms of the machine and, included in these operated mechanisms, is a rocker 12 to which a reciprocating movement is imparted. A link 13 interconnects the rocker 12 and an arm 14, which arm is mount-ed on the sleeve 15 that is rotatably mounted on the shaft 16 journaled in the frame 10, Fig. 2. On the sleeve 15 is a ratchet 1'7, connected to a gear 18, both of which are rotatable about the shaft 16. A retaining pawl 19 is pivotally mounted on the lug 20 that is a part of the frame 10. A. spring 21 is con nected to the pawl 19 and urges the pawl into engagement with the teeth of the ratchet 1'7 to prevent movement of the ratchet in a counterclockwise direction. A shaft 22 is fixedly mounted in the lug 29 and a sleeve 23 i rotatably mounted thereon. Fixed on the sleeve 23 is a pinion 24 which meshes with the gear 18. Also mounted on the sleeve 23 is a gear 25 which meshes with a pinion 26, mounted oh the shaft 16, to which pinion a disk 27 attached. Connected to thearm 1 1 is a bracket 29 on which a pawl 30 is pivotally mounted, a 31 extending between the braclzet 29 and the pawl 39 to seat said pawl in the teeth of the ratchet 1'7. When the arm l-i moves in a clockwise direction the bracket 29 moves in a similar direction and the pawl 30 moves the ratchet 17 in an amount sufficient to unseat th pawl 19 from one tooth of the ratchet and seat the pawl in a succeeding tooth and, after this amount of movement has been imparted, the arm. 14 moves counter-clockwise thus moving the bracket 29 in a similar direction, and the pawl 39 merely rides over the ratchet 17, the pawl 19 preventing movement of said ratchet. When the pawl 30 is so moved the gear train comprising the gear 18, pinion 24, gear 25, and pinion is motivated, and the disk 27 rotates one complete revolution. Pivotally mounted on the fre 1e 10 is a rocker 32. One end of the arm 33 1S civotally connected to one end of the rocker 32 and the other end of the arm 33' is supported by the uide roller 3% rotatably mounted on the frame 10, a rack 35 being provided on the upper surface of the arm 33 at the last named end. Jcurnaled in the frame 10 is a stud shaft 36 having a split collar 37' at one end to prevent endwise displacement of the shaft. On the periphery of the shaft 36 is a gear segment' 3'? meshed with the rack and. opposite the gear segment 37, the 36 is cut away to provide a flattened portion 38 through which one end of an arm 3911s extended, said arm 39 being pivotally mounted on the frame 10, as indicated at 40. A spring 41 acts on the arm 39 to force said arm into engagement with the flattened portion 38.

Mounted on the arm 39, at the end thereof, resting on the flattened portion 38, is an accumulating numbering device 12 of the usual construction, the particular construction of this device forming no part of my invention. The numbering device 42 includes an operating arm 43 which is bifurcated, as indicated at 14, to receive the roller 45 carried by the crank arm to mounted on the shaft 36. When the arm 43 is actuand auxiliary printing mechanism.

ated the numbering device is caused to accumulate, preferably one unit. The numbers on the various wheels of the accumulating device preferably in the form of type so that a printing operation may be performed therefrom. The numbering device 42 is disposed below the usual ribbon, indicated by 47, commonly provided in machines of this character. The ribbon 4'? is arranged at the printing position of the machine through which position the printing devices 48 are passed. These printing devices 13 are moved through a guideway 49 by the feed bar 50 which, in the present instance, has a lug 51 depending therefrom to which one end of an. operating arm 52 is connected, said arm 52 being operable from the arm 14. When the arm M moves counterclockwise, as viewed in Figs. 1 and 4, the feed bar 50 is moved rearwardly or toward the magazine 53 in which the printing devices 48 are arranged prior to passage through the machine and when the 14 moves clockwise, as viewed in Figs. 1 and i, the feed bar 50 is moved forwardly to advance new printing device into printing position. During the time the feed bar 56 is moving rearwardly the printing devices 48 are at rest and the printing mechanism, generally indicated by 54, is actuated to perform a printing operation. In the present instance the printing mechanism 54 is a roller platen of the type dis closed in the alluded to Duncan patent, but it is to be understood that a reciprocating stamper arm or other arrangement might be provided to perform the printing operation from the printing device and the numbering device. The platen performs the printing operation by forcing the sheet S, which will be the bill or the like, toward the printing device and the auxiliary printing mechanism, the ribbon d7 being interposed between the sheet and the printing device When a printing operation is not being performed from the numbering device, it is urged into a lower position out of engagement with the ribbon 47 by the spring 11. When a printing operation is to be performed the numbering device is elevated into engagement with the ribbon and during such elevation it is caused to accumulate. To bring about this elevation and accumulation the rocker 32 is'actuated by therod 55, pivotally connected to the rocker 32 at the end thereof opposite the connection of the arm 33. A spring 56' extends between the arm 55 and the frame 16 and urges the arm downwardly into engagement with the stud 56 on the disk 27. In the arm 55 is a notch 57. As will be described hereinafter, the numbering device does not elevate and accumulate upon every operation of the disk 2'7. At the end of an operation of the disk 27, during which the numbering device is not elevated and accun1u-- lated, the stud 56 and notch 57 occupy the position shown in Fig. 1. However, at the end of an operation in which the numbering device is elevated and accumulated, the stud 58 comes at rest. in the position shown in Fig. 1 and notch 57 is resting thereon. Thu:- when the disk 2'! is rotated in the direction of the arrow, Fig. 1, the

stud 56 seats in the notch 5'? and the arm 55 is reciprocated and the rocker 32 is moved.

When the rocker 32 is moved the arm 83 will be moved toward the right, as viewed in Fig. 1, and, by reason of the interconnection between the rack 35 and the gear segment 37, the shaft 36 will be rotated in a clockwise direction. This causes the flattened portion 38 to move frorn the downwardly inclined position of Fig. 1 into an upwardly inclined position to elevate the arm 39 which moves the printing device into engagement with the ribbon 47. This movement of the shaft 36 is transmitted through the crank arm 46 to the roller 45 which moves through the bifurcation 44 to operate the arm 43 to cause the numbering device to accumulate. The stud 56 always stops in the position illustrated in Fig. 1 and it moves from this position in the direction of the arrow in Fig. 1 and when the notch 57 engages the stud 56, the arm is moved toward the right until the stud 56 moves into. the horizontal center plane of the disk 27 on the right hand side thereof, as viewed in Fig. 1. As soon as the .zcntal centerplane of the disk 27, the arm 55 will be moved toward the right and the numbering device will be lowered by this movement of, the arm 55 to the right and as soon as the numbering device is lowered, it is disengaged from the ribbon 47. In the foregoing manner the numbering device e2 will accumulate and be moved into printing position upon each operation of the feed bar 50, and this will occur, unless otherwise prevented, during the forward movement of the arm 52, when a new printing device is being'moved into printing position, or every time a printing device moves through printing position. However, a printing device may be passed through printing position and the numbering device will not be operated. To accomplish this, I provide below the guideway 49 detecting 'pawls 58 and 59. One of these pawls is illustrated in Fig. 7 and, by referring thereto, it may be seen that the pawl has an elongated slot 60 at one end with which slot a reduced passage 61 communicates, said passage 61 extending through the upper edge of the pawl. Depending from the pawl, at the opposite end, is a nose 62, and at substantially the medial portion of the pawl on theupper edge is a lug 63. Both pawls are formed in this manner. Extending across the guideway 49 are two pins 64 and 65, Fig. 5,which are arranged in horizontal alinement. In order to install the pawls 58 and 59 in position the pin 64 is first passed through the passage 61 and. then the pawl is turned to permit passage of the pin 65 and, in this manner, the pin 64 will'be disposed at the forward end of the slot 60 while the pin 65 will be disposed in alinement with the passage 61. Therefore, each of the pawls 59 and 60 will be supported in horizontal position and will be free to be cammed downwardly in a manner now to be described:

0n the printing devices 48 are juxtaposed, lugs 66 and 67 which are adapted to receive and retain the limb portions 68 and 69 of the switch tab 70. This switch tab 70 may be disposed either in the position X or the position Y, Fig. 6. The pawls 58 and 59 are arranged inside by side relation. When a switch tab is in the position X it is alined with the pawl 59, and when disposed in the position Y it is alined with the pawl 58. A bar 71 extends between the members 72 and 73 providing the guideway 49. On the bar 71 is a collar 72' supporting a lug '73. Connected to the lug 73 are superimposed'blocks of insulating material 74, and 76. Disposed between the blocks 74 and 75 and extending therefrom is a yieldable contact carrying arm 77. Disposed between the blocks 75 and 76 and extending therefrom is a yieldable contact carrying arm 78. On the arm 77 is a contact 79 and on the arm 78 is a contact and these contacts are normally in engagement with each other. Extending from the arm 77 is an extension 81 onwhich the nose portions 62 of the pawls 58 and 59 are rested, Fig. 5. It has been pointed out that the pawls 58 and 59 are removably mounted and, therefore, either or both of these pawls may be disposed in position. If, for example, only the pawl 59 is arranged in position it is apparent that only the printing devices having the switch tab 70 in the position X will cause operation since operation iscaused by the engagement of one of these tabs with one of the lugs 63. Therefore, when the switch tab '70; in the position X, engages the lug 63 on the pawl 59, said pawl will be forced downwardly and the nose portion 62 thereof will force the extension 81' downwardly to so move the arm 77 and thus the contacts 79 and 80 will be separated. Since the pawl58 is not in positiomit is apparent that switch tabs 70 in the position Y will not cause separation of the contacts 7 9 and 60 in this manner. Mounted on the frame 10 below the magazine 53 is a switch 81 including an operating pin 82. On the arm 52 is a boss 83 and when the arm' 52 is moved into the rearward position the boss 83 engages the pin 82 and moves thispin to close the switch 81, said switch normally being open. On the frame 10 is a solenoid 84 including an armature 85 to which a link 86 is pivotally connected. Pivotally mounted on the frame 19 is an arm 87 to the medial portion of which the link 66 is connected. In thearm 87 is, a recess defining a shoulder 89. Pivotally mounted on the shaft 22 is a bracket 90 including an arm 91 on which a roller 92 is mounted, said roller .92 being forced into engagement with the periphery of the disk 27 by the spring 93 that extends between the bracket 90 and a spring anchor on the frame 19. The bracket 90 includes an arm- 94 having a hook portion 95 at one end thereof. On the arm 871s a stud 96 and the spring 93 normally holds the arm 94 inengagement with this stud 96. A stud 97is provided on the arm 55 in alinement with I the recess 88. If, as above stated, a printing device 48 moves into position over the pawls and the tab-70 thereon is in the position Y when the pawl 58 isremoved, it is apparent that the contacts 79 and 80 will not be separated. Therefore, when the arm 52 moves rearwardly and the boss 83 engages the pin 82 the switch 81 will be closed and, in this manner, an electric circuit will be closed to energize the solenoid 84. This circuit as follows:

- The line leads are indicated by 98 and 99 and a switch 100 closes the circuit between these leads 98and 99110 the motor leads 101 and 192 to set the motor 11 in operation, the switch 199 being" located at an accessible place on themachine. Also mounted at an accessible place on the machine is a switch 103 connected to the motor leads 101 and 102 by the conductors 104 and 195. A conductor 106 interconnects one terminal of the switch 103 with a contact plate107. A conductor 108interconnects the contact plate 107 and one terminal of the switchSl.

A conductor 112 interconnects the other terminal of the switch 81 with a contact plate 113.

A conductor 11% interconnects the contact plate; 113 with the winding of, the solenoid 84, the

other end of the winding of the solenoid being connected by a conductor 115 to a contact plate 116. A conductor 11'? interconnects the other terminal of the switch 103 and the contactplate 116. The switch 103 controls the operation of my improved auxiliary printing mechanism. When the switch 103 is closed and when the contacts '79 and and the switch 81 are closed the following circuit is closed from one terminal of the switch 103, through conductor 106, contact plate 197, conductor 103, contact '79, contact 80, conductor 109, contact plate 110, conductor 111, switch 31, conductor 112, contact plate 113, conductor 114, winding of solenoid 84, conductor 115, contact plate 116, conductor 117, to the other terminal of the switch 193, and thus the solenoid 3 1 is energized which attracts the armature thereof that moves to compress the springs 118 and 119 which normally hold the armature 85 in the position illustrated in Fig. 1.

When the armature 85 is moved, as above, the

arm 8'7 is pivoted and the lug 96 is engaged by the hook portion 95 and the arm 87 is held against movement toward the right. Therefore, when the disk 2'7 rotates, during forward move:

ment of the arm 52, and the stud 56 enters the notch 57 the arm 55 will be moved only a short distance until the lug 9'7 engages the arm 87 which, as stated, is held against movement and, therefore, the stud 56 will ride out of thenotch 5'? and the arm 55 will not be operated to elevate the numbering device 42. The periphery of the disk 27 provides a cam embodying a rise 120.

This rise 120 engages the roller 92 prior to the,

time the parts move into their at rest position shown in Fig. 1 and when the roller 92 engages this rise the bracket will be pivoted to dispreviously described manner unless prevented by operation of the solenoid 84 in the manner explained.

It has been statedthat a particular use of this machine is in the printing of the variable information on tax bills and the numbering of these tax bills to correspond with the numbering on an assessment roll. When a new assessment roll is made up and numbered the printing devices are arranged in the same sequence as the sequence of the items on the assessment roll and the numbering device 42 is adjusted so that itwill print numbers on the tax bills simultaneously with the printing of the information from the printing devices. The switch tabs 70 on the printing devices will all be set in a corresponding position as, for example, the position X. One of the pawls 58 or 59 will be removed and, if the switch tabs are in the position X, the pawl 58 will be removed. Therefore, as the printing devices are passed through the machine the numbering device will operate as eachprinting device passes through the machine since the various tabs '70 will successively engage the lug 63 on the pawl 59 to cause separation of the contacts '79 and 80. However, when new printing devices areadded, under the conditions previously set forth it is necessary that the numbering device not be operated when these added printing devices pass through the machine in order that the proper sequence of numbering will be maintained;v Therefore, the switch tabs '70 on the newly added printing devices will be disposed in the position; Y- and when a printing device having the switch tab in this position Y moves into position abovethe pawls, itis manifest that the contacts '79- and 80 will not be separated by reason of the fact that the pawl 58 is removed. Therefore, the circuit to the solenoid 84 will be closed whichwill prevent operation of the numbering device in the manner previously described. It is, therefore, apparent that the proper sequence of numbers may be retained even though new printing devices are added. When a new assessment roll is to be made up both the pawls 5B and 59 will be; installed. I'herefore, every printingdevice having a tab 70 thereon, which passes through the machine will cause operation of the numbering device and, by employing a suitable listing attachment on the machine, the assessment roll may be made up from the printing devices and the numbering devices. This assessment roll is usually made up about the middle of the year preceding the year for which theroll is to be used and, therefore, after the assessment roll has been made up the added pawl, which, in this instance, would be the pawl 58, will be removed, and it is therefore apparent that only the printing devices with switch tabs in the position X will cause a printing operation.

When both pawls are in position every printing device passing through the machine will not necessarily cause operation of the solenoid 84 since a printing device not having a switch tab 70 thereon will not cause the energizing of the solenoid. In order to prevent operation of the printing mechanism at any desired time, as for example, when a printing device having the switch tab in the position Y is passed through the machine, the selector mechanism, commonly provided on printing machines of the character referred to, may be used. When all the printing operations have been performed from the printing devices arranged to print in accordance with one assessment roll and it is desired to print in tion, either the position X or the position Y,

and the proper pawl will be installed. It is, therefore, apparent that proper operation will result as printing devices not to be numbered,

ill.

which have switch tabs 70 thereon, may have the switch tabs '70 thereof moved into the other position. When the printing devices are employed in the printing of tax bills it is manifest that property represented by the items onthe assessment roll may be sold or otherwise trans-.

ferred, and it will, therefore, be desirable to have the new owners name appear. This may be accomplished by employing printing devices on which the printing plates are detachably mounted and, for example, the legal description of the property may be arranged on one plate while the ranged on the printing. device. One 'form of printing device which may be used for this purpose is disclosed in the Duncan Patent No. 1,654,040, patented December 2'7, 1927.

While I have described this invention for use in connection with. tax bills, it is to be understood that the invention is susceptible to many other uses and it is apparent that another similar mechanism might be substituted for the numbering device, and such other uses and changes are intended to be Within the scope of my invention. l

While I have illustrated and described a preferred form of construction for carrying my invention into effect, it is to be understood that this is capable of variation and modification without departing from the purview of the following claims.
